    ExtraHeaders Property (ZippedFile)
    In This Topic
    Gets or sets the file's extra headers.
    Syntax
    'Declaration
 

    Public Property ExtraHeaders As ExtraHeaders
    'Usage
 

    Dim instance As ZippedFile
Dim value As ExtraHeaders
 
instance.ExtraHeaders = value
 
value = instance.ExtraHeaders
    public ExtraHeaders ExtraHeaders {get; set;}

    Property Value

    An ExtraHeaders value representing the file's extra headers. If the extra headers are read from an existing zip file, the ExtraHeaders property will reflect the known extra headers currently stored in the zip file. Otherwise, new instances will use the ZipArchive.ZipArchive.DefaultExtraHeaders.
    Remarks

    The zip file will automatically be updated when the value of the ExtraHeaders is changed. If batch modifications are to be made to the zip file, it is recommended that they be made between calls to the ZipArchive's BeginUpdate and EndUpdate methods.

    By default, a zip file created with a version of Xceed Zip for .NET prior to 2.2, WinZip, or Windows XP Compressed Folders, among others, will only preserve the last modified date and time.
